What Is the Function of the Respiratory System

The respiratory system is a very vital system in the living beings for survival. It is a process of the exchange of gaseous materials in the body for its functioning. The pattern of the respiratory system differs from plants and animals. Even among animals, the respiratory pattern differs from one class of animals to another according to the family it belongs. This article would speak about the functioning of the respiratory system in human beings and its functions.

The major body parts of the respiratory system include the Nose, Trachea (Wind pipe), the lungs, and the alveoli in the lungs. These parts of the body help in the functioning of the respiratory system among mammals for the supply of oxygen to the blood. Firstly, the process of respiration is an involuntary process done by the brain. Hence, it is done unconsciously. In the brain there is a central regulatory system that creates the working of the respiratory system in the body.

There are multiple functions of the respiratory system. The earth in which we are living is made by many gases like the carbon dioxide, nitrogen, oxygen and others. But, for our survival, we need oxygen. Without the supply of oxygen to the body, the other processes do not work, thus leading to death.

Hence, the first function of the respiratory system is to provide oxygen to the body through the process of inhalation. Once the air is inhaled, the tiny air strands in the naval cavity would filter out the dust. The air enters into the body and then moves through the trachea to reach the lungs. The lungs have a small grape like structures called the alveoli that extracts the oxygen from air inhaled through the process of diffusion. The unwanted carbon dioxide is exhaled out.

Then, this oxygen absorbed by the body is mixed with the blood pumped out by the heart. Then, the heart takes care of the oxygenated blood circulation throughout the body. Thus, the source for the functioning of the body is performed by the respiratory system. The exchange of gases is the main function performed by the respiratory system.

This process of respiration is different in other class of living beings. For example, the respiratory system in the aquatic animals is with the help of gills that has the ability to absorb oxygen from water. This respiratory process is different in amphibians. The amphibians can extract oxygen in water or even on land for its survival. Thus, they can live in water and on land. Hence, the respiratory process is very important for the survival of all living beings.
